Essential Code (USE THIS)

核心代码（请使用这段代码）

GitLab Token Verification (JavaScript)

GitLab令牌验证（JavaScript）

javascript

function verifyGitLabWebhook(tokenHeader, secret) {
  if (!tokenHeader || !secret) return false;

  // GitLab uses simple token comparison (not HMAC)
  // Use timing-safe comparison to prevent timing attacks
  try {
    return crypto.timingSafeEqual(
      Buffer.from(tokenHeader),
      Buffer.from(secret)
    );
  } catch {
    return false;
  }
}

javascript

function verifyGitLabWebhook(tokenHeader, secret) {
  if (!tokenHeader || !secret) return false;

  // GitLab uses simple token comparison (not HMAC)
  // Use timing-safe comparison to prevent timing attacks
  try {
    return crypto.timingSafeEqual(
      Buffer.from(tokenHeader),
      Buffer.from(secret)
    );
  } catch {
    return false;
  }
}

Express Webhook Handler

Express Webhook处理器

javascript

const express = require('express');
const crypto = require('crypto');
const app = express();

// CRITICAL: Use express.json() - GitLab sends JSON payloads
app.post('/webhooks/gitlab',
  express.json(),
  (req, res) => {
    const token = req.headers['x-gitlab-token'];
    const event = req.headers['x-gitlab-event'];
    const eventUUID = req.headers['x-gitlab-event-uuid'];

    // Verify token
    if (!verifyGitLabWebhook(token, process.env.GITLAB_WEBHOOK_TOKEN)) {
      console.error('GitLab token verification failed');
      return res.status(401).send('Unauthorized');
    }

    console.log(`Received ${event} (UUID: ${eventUUID})`);

    // Handle by event type
    const objectKind = req.body.object_kind;
    switch (objectKind) {
      case 'push':
        console.log(`Push to ${req.body.ref}:`, req.body.commits?.length, 'commits');
        break;
      case 'merge_request':
        console.log(`MR !${req.body.object_attributes?.iid} ${req.body.object_attributes?.action}`);
        break;
      case 'issue':
        console.log(`Issue #${req.body.object_attributes?.iid} ${req.body.object_attributes?.action}`);
        break;
      case 'pipeline':
        console.log(`Pipeline ${req.body.object_attributes?.id} ${req.body.object_attributes?.status}`);
        break;
      default:
        console.log('Received event:', objectKind || event);
    }

    res.json({ received: true });
  }
);

Python Token Verification (FastAPI)

Python令牌验证（FastAPI）

python

import secrets

def verify_gitlab_webhook(token_header: str, secret: str) -> bool:
    if not token_header or not secret:
        return False

    # GitLab uses simple token comparison (not HMAC)
    # Use timing-safe comparison to prevent timing attacks
    return secrets.compare_digest(token_header, secret)

For complete working examples with tests, see:

python

import secrets

def verify_gitlab_webhook(token_header: str, secret: str) -> bool:

Recommended: webhook-handler-patterns

推荐搭配：webhook-handler-patterns

We recommend installing the webhook-handler-patterns skill alongside this one for handler sequence, idempotency, error handling, and retry logic. Key references (open on GitHub):

Handler sequence — Verify first, parse second, handle idempotently third
Idempotency — Prevent duplicate processing
Error handling — Return codes, logging, dead letter queues
Retry logic — Provider retry schedules, backoff patterns

我们推荐搭配webhook-handler-patterns技能一起使用，以获得处理器流程、幂等性、错误处理和重试逻辑的最佳实践。关键参考资料（在GitHub上查看）：

Handler sequence — 先验证，再解析，最后进行幂等处理
Idempotency — 防止重复处理
Error handling — 返回码、日志、死信队列
Retry logic — 服务商重试计划、退避模式
